1997 first edition, first printing hardcover and dust jacket. Slight wrinkling on first few pages. ; 1.4 x 9.8 x 6.4 Inches; There is only one John Douglas.

We first met Douglas in Mindhunter, which told the story of his brilliant and terrifying with the FBI until his retirement in 1995. And now, again with coauthor Mark Olshaker, he goes even further. We accompany him on the Journey Into Darkness that marks every case he examines; every instance in which he helps police identify the unknown perpetrator of a violent series of rapes, kidnappings, or murders through his remarkable criminal personality profiling.
